I had this technology shown to me ten years ago by Tony Bongiovi, yes, Jon Bon Jovi’s uncle. It’s pretty remarkable and sounds just as full as you would hope.

Efficiency gains are great, but the bigger gains are to be had in manufacturing, installation, and overhead costs. If we’re just talking residential, companies spend a couple thousand in customer acquisition costs per installation. The utility scale stuff is MUCH cheaper per kW, but can still wring out some more savings in siting, permitting, interconnection, and overheads. Panel efficiency gains tend to help more when space is more of a concern. If you can spread out, then much cheaper, less efficient panels are often the better choice.

Yeah it’s the “first” step on a unique form of speaker, unlikely to have the audio fidelity of high end speakers but interesting to see none the less.

How about using thermoelectric coupler underneath it to absorb the heat and turn it to energy, will that increase the percentage?

Flat panel speakers are nothing new. Dayton Audio (https://www.daytonaudio.com/topic/excitersbuyerguide) sell exciters you can put on any surface to make it into a loudspeaker. The sound quality highly depend on the material you put it on. As a general rule, do not expect high quality sound unless the material is optimal. There are several videos on Youtube which demonstrate them. A great one here: https://www.youtube.com/watch?v=XC814uQjlaE&t=1562s&ab_channel=AmplifyDIY
The news from LG is that they apparently have designed a new type of exciter. Do not expect miracles.

Finally a speaker made out of the same material that navy seals are.

Oh God, imagine the vibrations of various parts. As a former auto-audiophile, the amount of time and money I had to spend putting sound deadening in places makes me feel like this is a really bad idea

Can they make it inaudible too?

I don't really see why there needs to be a special space-saving design where there's plenty of space for speakers, what else would you put there?

As a bit of an audiophile I’m not entirely convinced that the quality of the sound would be any good - but I’d be keen to be proven wrong.

Would like to know what they sound like? Do they have any bass? Or would they be tinny.

There’s one a couple of blocks away from me. Looks pretty slick. That said, it’s the only one I’ve ever seen and they have 2 Teslas, if that tells you anything.

Or an electric car. Then again you save on gas.

It would have to actually exist in reality for it to be an option

There are many free online estimators where you can enter your exact location and the number of panels or peak power installed (17 panels x 400W = 6.8kW peak power) and it will calculate month by month generation. Some even take into account a typical weather patterns.

I guess this is good for the tech as a whole but from what I remember in doing my masters thesis on solar cells, these records are produced using really tiny cells and the efficiency figures don't hold up at all as you scale them up.

Think forward. Speakers complicate aerodynamics, sound proofing, and add weight where you do not want weight. Cars are just drones that don’t know how to fly yet. We’ll all want to be wrapped in the most aerodynamic space and weight conscious vehicles possible, because it’s going to be a balance between comfort, range, and economics.
